The diagnosis is typically based on finding low blood magnesium levels, also called hypomagnesemia. [6] Normal magnesium levels are between 0.6 and 1.1 mmol/L (1.46–2.68 mg/dL) with levels less than 0.6 mmol/L (1.46 mg/dL) defining hypomagnesemia. [1] Specific electrocardiogram (ECG) changes may be seen. [1]
Approximately 1% of total magnesium in the body is found in the blood. [23] Magnesium is important in control of metabolism and is involved in numerous enzyme reactions. A normal range is 0.70 - 1.10 mmol/L. [23] The kidney is responsible for maintaining the magnesium levels in this narrow range.
Diagnosis is based on a blood level of magnesium greater than 1.1 mmol/L (2.6 mg/dL). [1] [3] It is severe if levels are greater than 2.9 mmol/L (7 mg/dL). [5] Specific electrocardiogram (ECG) changes may be present. [1] Treatment involves stopping the magnesium a person is getting. [2]
When the amount of magnesium levels in the blood falls below the normal level (1.3 to 2.1 mEq/L), a person is experiencing hypomagnesia, or magnesium deficiency. [2] A majority of people surveyed in the United States report lower daily intakes of magnesium than what is recommended. [1]
"Blood tests only measure the amount of magnesium in the blood, which is a small percentage of the total magnesium in the body, so it's not an ideal way to determine magnesium levels in the body ...
Normal potassium levels are between 3.5 and 5.0 mmol/L (3.5 and 5.0 mEq/L) with levels below 3.5 mmol/L defined as hypokalemia. [21] [28] It is classified as severe when levels are less than 2.5 mmol/L. [21] Low levels may also be suspected based on an electrocardiogram (ECG). [21] Hyperkalemia is a high level of potassium in the blood serum. [21]
Magnesium is important to the health of your bones, heart and brain. It's great to get it via food, but here's the best time to take magnesium supplements.
Serum levels are typically 0.7–1.0 mmol/L or 1.8–2.4 mEq/L. Serum magnesium levels may be normal even when intracellular magnesium is deficient. The mechanisms for maintaining the magnesium level in the serum are varying gastrointestinal absorption and renal excretion. Intracellular magnesium is correlated with intracellular potassium.
